162 NATURAL HISTORY CALENDAR. 
Tue Insects or May.—During this month there is great activity 
among the insects. As the flowers bloom and the leaves appear, mul- 
titudes wake from their long winter sleep, and during this month pass 
through the remainder of their transformations, and prepare for the 
summer campaign. Most insects hybernate in the chrysalis, or pupa, 
state, while many winter in the caterpillar or larva state, such as the 
larve of several Noctuide and the ‘yellow-bear,” and other cater- 
pillars of Arctia and its allies; while many insects hybernate in the adult 
or imago form, either as beetles, butterflies, or certain species of bees. 
It is well known that the Quoi Humble Bee winters under the 
moss, or in her old nest. During the present month her rovings seem 
to have a more definite object, and she seeks some deserted mouse- 
nest, or hollow in a tree or stump, and there stows away her pel- 
lets of pollen, containing two or three eggs apiece, which, late in the 
summer, are to form the nucleus of a well-appointed colony. The Car- 
penter Bees, Ceratina and Xylodspa; the latter of which is found in 
abundance south of New England, is bus and tunnelling
